Background technology
Trichiasis refer to that eyelashes rearward grow, so that touch the disease of eyeball.Trichiasis are children, external ophthalmopathy more common in teenager and old people, and mainly the direction of growth of eyelashes occurs abnormal.Under the friction that eyelashes are long-term, conjunctival congestion, corneal epithelium point-like or diffuse damage or corneal epithelium partial exfoliation, cornea shallow-layer muddiness, cornea rebirth blood vessel, corneal pannus, corneal epithelium are thickening, corneal epithelium keratinization, corneal ulcer, corneal leukoma cause visual deterioration even severe patient cause blind.
The reason of trichiasis is a lot, and child and the teenager direction of growth mainly due to eyelashes is abnormal, the superfluous skin of lower eyelid, the epicanthus of epiblepharon inferior associating sometimes, and geneogenous entropion causes.Middle-aged and elderly people is mainly caused by the inflammation of conjunctiva palpebrae and margo palpebrae portion cicatricial contraction, and blepharitis, trachoma, the entropion that a variety of causes such as wound cause.Cause the reason of trichiasis to mainly contain two classes, comprise the trichiasis without entropion and the trichiasis with entropion.Entropion necessarily can cause trichiasis, but trichiasis differ establishes a capital with entropion, and trichiasis can individualism.
The methods such as the locality trichiasis of the negligible amounts without entropion, conventional Therapeutic Method has: machinery is pulled out, electrolysis, cold therapy, laser ablation, microscope resection hair follicle.A fairly large number of and with the patient of entropion for trichiasis, conventional operation method has: lower fornix suture line of skin art, skin blepharosphincterectomy, orbicularis oculi desmopyknosis, excision of tarsal plate by wedge resection (Hotz art), tarsotomy, the methods such as margo palpebrae gray line otomy.
For complexity trichiasis, the degree of such as entropion trichiasis is in the inconsistent case of whole margo palpebrae, and the case that other entropion trichiasis postoperative straightenings also have part trichiasis to fail to correct, and the relapse rate of various therapeutic modality is all higher, and postoperative curative effect is not fully up to expectations.In recent years, margo palpebrae gray line otomy, as a kind of important rectification mode, obtains and pays close attention to widely.
Margo palpebrae gray line otomy is the gray line place of intermarginal portion in margo palpebrae, cut-away portions or whole intermarginal portion, margo palpebrae cut open and be divided into front layer and rear layer, intermarginal portion otch is fully opened, and the eyelid front layer in margo palpebrae district leans forward, make trichiasis away from eyeball, to reach the object of correcting trichiasis.In recent years, gray line otomy, as a kind of important rectification mode, obtains and pays close attention to widely.
In margo palpebrae gray line otomy, several large problem existed at present is as follows:
When 1, cutting margo palpebrae gray line open with knife blade, especially strictly accurate requirement is had to the degree of depth of cutting, the scope that gray line cuts should exceed each 2mm in two ends, trichiasis region, the degree of depth is about 4mm, after implant is placed in incision site, sew up continuously with 8-0 or 9-0 nylon wire, by the end of a thread ligation at margo palpebrae anterior lip, in order to avoid touch cornea and conjunctiva, be coated with antibiotic ophthalmic ointment 7 to 10 days until removal of suture.The knife blade of current clinical middle use does not have scale, and cannot meet the requirements of the cutting degree of depth accurately, incisxal edge is irregular, and intraoperative hemorrhage is many, and operating time is long, and efficiency is low, have impact on surgical quality and postoperative effect.
2, the knife blade that uses at present of ophthalmology, is single-blade structure, can only unidirectionally cuts during operation, if when needing reverse cutting, can only reverse blade or tool changing, operating time is long, wound is large, adds the misery of patient.
Often need the eyeball of patient rotate to some direction and keep fixedly watching attentively in the operation of 3, ophthalmology, be beneficial to the carrying out operated.But the knife blade function of current clinical middle use is simple, does not guide eyeball to each azimuth rotation and the function of fixedly watching attentively, the needs of ophthalmologic operation can not be met, thus bring great inconvenience to clinic diagnosis and surgical work.Such as when doing margo palpebrae gray line cutting operation, if the motion of patient's eyeball is uncontrollable in operation, hinder the operation of operation, careless manipulation even can be stabbed cornea or be pierced through anterior chamber, causes the perforation of cornea complication that even the blind grade of eyeball is serious.
Summary of the invention
The purpose of this utility model overcomes prior art shortcoming, there is provided a kind of rational in infrastructure, easy for operation, once descend cutter accurately controlling on the basis of the cutting degree of depth, margo palpebrae gray line cutting operation can either be completed, eyeball can be guided again to each azimuth rotation also to keep the margo palpebrae gray line cutting blade of fixedly watching attentively.
The technical solution of the utility model is: a kind of margo palpebrae gray line cutting blade of fixedly watching function with eyeball attentively, comprise blade body, described blade body is provided with the holddown groove of hollow out, it is characterized in that: the head of described blade body is provided with symmetrical two-sided blade, described blade body is provided with graduation mark, and the afterbody of described blade body is provided with elastic memory steel wire.
Described graduation mark is in units of millimeter, and equidistant setting, symmetrical is distributed on the positive and negative of blade body.
Described steel wire end enlarges into the spherical mark as fixedly watching attentively.
The advantage that this utility model has and good effect are: owing to being provided with two-sided blade at the head of blade body, when doing margo palpebrae gray line otomy, can according to the needs of operation forward or oppositely cutting margo palpebrae backward, do not need reversion blade or tool changing, enormously simplify surgical operation step, shorten operating time, alleviate the misery of patient; In addition, because blade is with the scale in units of millimeter, in operation process, doctor can observe the concrete degree of depth of lower cutter very intuitively, can grasp the degree of depth of cutting, thus can make the accurate margo palpebrae gray line incision of the degree of depth, improves the success rate of operation.The memory steel wire with fixation function can guide eyeball rotate to all directions and keep fixedly watching attentively, brings great convenience to operation process.
